My sister has one, and I tried it at her place about a year ago. It is definatly low-impact, so you wont hurt your knees or anything doing it. I don't thing it will get your heart rate up toooo much, but my sister did lose 14 lbs in 2 months using it. She just plops it in front of the tv and does it for like an hour straight. I'm sure there are DVD's that come with it too that show you how to get a better workout out of it. I'm not sure this was too helpful, but I think it is a good machine to have in the living room, so that you are getting in some cardio instead of sitting on the couch!

I own a gazelle. It was gift from my boyfriend at my request. This was Christmas of 2005. I have used it maybe 5 times, twice whole heartedly. Right now I am hanging 3 tank tops and 2 bras from the piston cylinders and handle bars. It works in that sense.

I have one and I really like it. It is the Freestyle. It has three settings, and I use it on the middle one. I definitely get a good work out on it. It can be boring (but I feel the same about the bike, treadmill, etc.) so I listen to books or music on my mp3 player while I use it. I feel that I get as a good a workout on it as I do walking at a 3.5 mph pace without really pushing myself. If I push, I am wringing with sweat when I am done. That being said, at almost 180 lbs and 50 years old - put everything I have said in perspective.

It did nothing for me. I was bored, and didn't feel like I got a good workout as much as I did a good stretch. I had the basic model. Amy 3FC loves hers, though. She has the model that has resistance options.

There is actually a Professional Version of the Gazelle in my gym...but it's a bit more, with 100 resistance settings and 10 inclines, it's called the Cybex Arc Trainer, it's like climbing uphill through mud when you get to a higher resistance setting...(i've worked my way to 30 mins. at level 42 varying the incline between 7-10). there is no hyper-extension with the pedals. it is an excellent workout, the trainer says it gives me more strength in my weak hip-flexors.
